DROP-VALVE FOR STEEP TUBS AND VATS.

SPECIFICATION forming part. of Letters Patent No. 311.24137, dated January 27, 1885.

Application filed October 31, 1884. (No model.)

To all whom t may concern..-

Be it known that I, JOHN IRLBACKER, of Buffalo, in the county of Erie and State ot' New York, have invented certain new and useful Improvements in Drop-Valves for Steep Tubs and Vats; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has general reference to drop-valves for steep-tubs; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

In the drawings already mentioned, which serve to illustrate my said invention more fully, Figure l is a longitudinal sectional elevation of my drop-valve, showing the latter in a closed position. Fig. 2 is an elevation, and Fig. 3 a plan, of the valve in an open position. Y

Like parts are designated by corresponding letters of reference in all the figures.

The object of my present invention is the production of a drop-valve for steep-tubs that can be readily opened and closed, and allows the drawing off of the steep water in the quickest possible time without interfering with the said valve. To attain this result I secure to the bottom of the steep tub or vat A, which bottom may be either flat or conical, as shown in the drawings, a anging-piece, B, having` a flange, B', to which I secure,by means of bolts h, a T- shaped casting, C, with its iiange C. This T- shaped piece forms the body proper of my drop-valve, and it has near its lower edge two lugs, c, to which is pivoted the fiap E by means of lugs or ears e and' a screwbolt, e. On the opposite side of the lugs c, near the flange C', I provide two more lugs, a, to which, or between which, I pivot a lockinglever, F, by means of a screw-bolt, b. This lever F has at a suitable position a projection, F', engaging a rib, f, on the -llap E, in such manner as to securely hold the same against a packing-ring, l?, set into the edge of the valve-body C, so as to make a tight joint with the said body.

On the body C there are two branches, (or one only,if desired) C, from whichthe wastepipe D leads the steep-water from the steeptub.

-In the interior of the valve-body G, I locate a perforated strainer, G, resting with its flange g upon the Hanging-piece B, as clearly shown in Fig. l. 'Ihis strainer is so much smaller in diameter than the internal diameter of the valve-body O as to produce an annular chamber, H, Fig. 3, which allows the steep-water to gather in the valve-chamber and to discharge readily from the waste-pipe D.

On the lever F there is a set-screw, f, which engages the rib j', Figs. l and 2, in such a manner that when said screw is tightened it locks the lever F in position, so as to prevent the latter being opened, accidentally or otherwise, when it is not desired that it should be so opened.

It will be readily observed that, owing to the depth of the annular chamber H, I am enabled to produce in the strainer G such a large number of perforations as to aggregate in area that of the discharge pipe or pipes D, so that the waste water, when drawn from the steep-tub, will pass through the strainer as fast as it can pass through the waste-pipe-a result that has not heretofore been successfully attained in any apparatus of the class described with which I am acquainted. It will be further observed that this result is a very essential one in steep -tubs where the steep-water has to be renewed frequently, and where saving of time is quite an essential factor in the cost of production of malt.

The entire apparatus can be readily produced at but a triiiing expense as compared with other apparatus for a like purpose as now 1n use.

Having thus fully described myinvention, I claim as new and desire to secure to me by Letters Patent of the United Statesl. As an improved article of manufacture, a drop-valve for steep-tubs, consisting, essentially, of the valve-casing C', having one or more branches, C, a hinged cover locked to said casing by means of the lever F, having IOO ed with a rib, f, of the pivoted looking-lever F, having the projection F, engaging said rib i5 f, and the looking-bolt f, to lock the said lever when the drop-bottom is shut, substantially as and for the obj eet stated.

In testimony that I claim the foregoing as my invention I have hereto set my hand in the 2o presence of t-Wo subscribing Witnesses.

JOHN IRLBACKER.
